How to fix "Fake_module : Addon missing 'bl_info' give bad performance!"
It means that you have a few non add-on python files in the following locations:

C:\Users\Administrator\AppData\Roaming\Blender Foundation\Blender\2.77\scripts\addons\raw_script.py


and

C:\Users\Administrator\AppData\Roaming\Blender Foundation\Blender\2.77\scripts\addons\tt_operators.py


You can tell that these files aren't add-ons because they don't include a bl_info somewhere at the top. A bl_info would look something (but not exactly like)

bl_info = {
    "name": "Some Add-on Name",
    "author": "something",
    "version": (0, 5, 6, 6),
    "blender": (2, 7, 2)    
}


these are from a failed installation of the TubeTool add-on, and can be safely deleted.
